OPERATION

Use wooden or plastic wedges (Fig .23-A) to

prevent pinching the bar and chain (Fig.23-B) in the

cut. Wedges also control felling.
When diameter of wood being cut is greater than

the bar length, make 2 cuts as shown (Fig 24).

WARNING.

Before making the final cut,

always recheck the area for bystanders,

animals or obstacles.

WARNING:

Never saw completely

through the trunk. Always leave a hinge

(Fig.22-F). The hinge guides the tree. If

the trunk is completely cut through,

control over the felling direction is lost.

Insert a wedge or felling lever in the cut

well before the tree becomes unstable

and starts to move. This will prevent the

bar from binding in the felling cut if you

have misjudged the falling direction.

Make sure no bystanders have entered

the range of the falling tree before you

push it over.

WARNING:

As the felling cut gets close

to the hinge, the tree should begin to fall.

When tree begins to fall, remove saw

from cut, stop engine, put chain saw

down, and leave area along retreat path

(Fig 17-A).
